Cloud Custodian C7n-Mailer

c7n-mailer is a Cloud Custodian notification tool that subscribes to an SQS queue populated by policy actions and sends notifications via SES email, Slack messages, or integrations with DataDog and Splunk. It enables teams to alert resource owners when Custodian policies detect policy violations.

Cloud Custodian C7n-Mailer is one of 6 APIs that Cloud Custodian publishes on the APIs.io network, described by an AsyncAPI event-driven specification.

Tagged areas include Alerting, Email, Notification, and Slack. The published artifact set on APIs.io includes API documentation and an AsyncAPI specification.

This event API exposes 2 operations across 1 channel, and defines 4 schemas. It is described by AsyncAPI 2.6.0, at version 1.0.0.

The API connects through a single server, https://sqs.{region}.amazonaws.com/{account-id}/{queue-name} (https).
